Your genome describes--in exquisite detail --your propensity toward character traits and disease. And even if we can't decipher much of it now, scientific advances will eventually decode enough to substantially affect your children's privacy –with whom you share a large chunk of your genome.

Further, recent studies suggest that the genomic anonymity relied upon by many companies to share your data may be quickly eroding, further exposing the consumer and their family's genomic data. Like the erosion of online privacy, personal genomics will eventually push society to reevaluate our notions of privacy. Until then, personal genomics companies need to be especially vigilant in protecting our privacy.
